T all {Oil/Om it may concern:

Be it known that I, STANLEY W. HAYES, United States citizen, residing in Richmond, county of ll ayne, State of Indiana, have invented the following described Improvements in'Derails.

This invention is a derail having lost motion connections between the derailing member and a connecting rod whereby motion of one assists motion by the other. The dei ng mes'ibcr may be hand operated serv through the lost mot-ion connections to rate a target, or it may itself be operated the said connections, but in either case t acts on acquiring momentum to deliver a hammer blow to said connections thus insuring completion of the stroke and jarring loose any mud, ice or other foreign matter which may have collected on the parts. The connections include an actuator with refer ence to which the derailing member is mow able, and which has abutment surfaces spaced from and opposed to abutment surfaces on the derailing member. It is through these surfaces that the hammer action is effected, since in either direction of move ment one of its abutment surfaces strikes the opposed abutment surface of the actu ator hammer blow as will be later described. where, thederail is hand operated, since it materially promotes ease of operation, and

whether the movement is initiated by the derailing; member or the connections, insures its completion as stated.

The invention also relates to the provision of latch automatically urged to locking position and to its incorporation in and correlation with the other parts of the derail.

In the single sheet of drawings, Fig. 1 is a planet the open derailerg' Figure 2 rear elevation corresponding to Fig. 1; ,Fi srure 3 a vertical sectionon line IlIIlI of Figure 2, and Figure a like section'on line Il -IV of Figure 3.

This invention finds its most satisfactory embodiment in a derail of, the type in which the derailing member swings to and fro-in the rail as in the structure chosen for illus trat'ion, which however must be understood not to be exclusive of other modes in whichthe inventionmight be applied.

. In the illustrated derail, base pro This is advantageous particularly Application filed December 5, 1822. Serial No. 604,981.

vided with front. and rearwalls 1, 2 and with side walls 3, 4-, from: which extend outwe reinforcing spike flanges 6, is covered by the roof 7 so as to form an inverted open bottomed be); closed at the top except for the openings in which the operating and latchin o; mechanism is mounted. The (lei-ailing member having; the derail block proper 8, the hand hold 8 and the eye-lugs 9 is mounted. to swing on or with the hinge pin 10 supported in the sides 3, 4-. A stop 11 (Fig. on rear wall 2 and roof part '7 serves to limit the rearward swing of the derailino' member. The actuator 12 is shown as a crank mounted on the hinge pin 10 coaxially with the derailing member, although it is not necessary that they should have the same axis. The actuator has a connection lug; 13 for pivotal attachment to the connecting' rod 14, the actuator and the derailin q' member being so mounted as to be capable of relative angular movement about the same axis These parts are provided with pairs of front and rear eo-actinp; abutment surfa es those on the actuator being indicated bv the numerals 15 and 16, and those on the derailing; member by 17 and 18. i The abutment surfaces on at least one of these parts are spaced so as to embrace the abutment surfaces on the other without being in contact with both at the same time and they are best placec symmetrically, those on the actuator with reference to the median plane of the actuator through its pivotal axis and those on the deraili'no member with referonce to a plane through'its pivotal axis and preferablv also through its center of gravity. It will be observed that the meeting surfaces of these abutments are not radial to the axis of the hinge pin 10, but such a relation. is not excluded.- 7 l 0n reference to Fig. 4, it will. be apparent that at the beginningof the stroke in either direction an abutment surface of each pair will be in contact and that on th operation of the actuator, or the swinging of the derailiug" mei'nberby hand, the inertia of rest of the derailing member will be overcome, and it will be raised to, or swung througl the point of unstable equilibrium acquiring momentum overrunning the actuator, if the actuator is actuating the derailing member, andin case moving with. reference to it,

so that the corresponding abutment surfaces will separate and the previously inactive abutment carried by the derailingvrnemberi inthe roof 7, through whichtheactuator projects, substantially the width of the actuator, allowing only for proper play, and that its walls 19, limit sidewise motion.

The connecting rod 14 leads to a switch stand or target stand of familiar construction such for instance as those shown in Patents No. 1,185,662 dated June 6, 1916 and 1,312,691 dated August 12, 1919.

The latch which I have incorporated in this derail, and which as stated tends to move to locking position, is preferably a gravity latch having members located in planes meeting at an angle,-its upper or looking part 21 being arranged in angular relation to its weighted tail 22, which over,

balances the latch into locking position, the latch straddling or spanning the hinge pin lOland be ng mounted to rock, in the vertical planejthereofand on a fulcrum constituted bythei'surface on surfaces 22 on the base against which the rear surface 22" of the latch bears, intothe' path of'the lug 23 car ried by the" derailing member acent the V hinge pin and having front and rear surfaces 24, 25, which when obstructed by the correv obvious from Figure spending front and rear surfaces or" the member 21 of the latch lock the derailing memherin closed'or open position as will be The latch'is thus loosely" mounted, the bearing surfaces 22,

22 being: unconnected, but is kept. in place by the base and pin and may have its forward rocking movement limited by opposed portionsfot' thecbase 21 as its rearward I movement is by luo; 27 and adjacentparts ofthebase. member 21 1s notsyminet-ricalwith respect *to the vertical plane through its aXisb ut face 24 is displaced to the rear and down rearward position on the/base,

It will be-observed that latch being limited by the downwardly'projecting flanges of the hole-in which itis located, the pivot 01? the latch being thus; relleved enon the same pin LIlCl' lI1 line has the advantage of simplicity and compactness. not however an'essential relation either as regards the derailing member and the actuator, as above pointed out, or asregards" either or both of these members and the latch. nor is it intended to limit the appli-.
